Hydrazide ligand, (Z)-N'-(6-oxo-1,10-phenanthrolin-5(6H)-ylidene)isonicotinohydrazide, 1 forms from a 1:1 Schiff base condensation reaction between isoniazid (INH) and 1,10-phenanthroline-5,6-dione (phendione). Ag+ and Mn2+ complexes with 1:2 metal:ligand stoichiometry are prepared: [Ag(1)2]NO3, [Ag(1)2]BF4 and [Mn(1)2](NO3)2. Polymeric {[Ag(1)(NO3)]}n has 1:1 stoichiometry and forms upon infusion of CH2Cl2 into a DMSO solution of [Ag(1)2]NO3. {[Ag(1)(NO3)]}n was structurally characterized using X-ray crystallography. Metal-free 1 and its 1:2 complexes exhibit very good, broad-spectrum antimicrobial activity and are not excessively toxic to mammalian cells (A549 lineage).

菲咯啉-异烟肼杂配体及其Ag +和Mn2 +配合物的合成及其抗菌活性。

酰肼配体(Z)-N'-(6-氧代-1,10-菲咯啉-5(6H)-亚烷基)异烟酰肼,异烟肼(INH)与1,10之间的1:1席夫碱缩合反应形成1种形式-菲咯啉-5,6-二酮(phendione)。制备具有1:2金属:配体化学计量比的Ag +和Mn2 +络合物:[Ag(1)2] NO3,[Ag(1)2] BF4和[Mn(1)2](NO3)2。聚合{[Ag(1)(NO3)]} n具有1:1的化学计量,并在将CH2Cl2注入到[Ag(1)2] NO3的DMSO溶液中时形成。{[Ag(1)(NO3)]} n在结构上使用X射线晶体学表征。无金属1及其1:2配合物表现出非常好的广谱抗菌活性,对哺乳动物细胞(A549谱系)没有过度毒性。
